Here is an excerpt from a web page about the 1964 New York Worlds Fair
Many of the World's Fairs were long remembered for a fast food sensation introduced at the exposition. The ice cream cone was introduced at St. Louis in 1904 and the 1964 New York World's Fair had the "Bel-Gem" waffle. Of course it orginated at the Belgium Village, but it was also all available all over the Fair. It was constructed of a fat, fluffy waffle base that was piled high with strawberries and topped with whipped cream. Best of all it was delicious.
Here are some things to do with Belgium Waffles and links to some recipes.
